This tech CEO has all the right credentials to steer a digital-music start-up.
In addition to degrees in computer science and economics from Stanford University, Prerna Gupta is expert in all things Britney Spears.
Gupta is a former beauty pageant winner who aspired to follow in the hip-hop dancing footsteps of her childhood idol, Spears. Now, as the 28-year-old CEO of Khush, the company behind a new iPhone app called LaDiDa, Gupta's performance background may help her as much as anything she learned in college.
LaDiDa works this way: compose a song, sing it into an iPhone or iPod Touch, and the software will provide the musical accompaniment. Think of it as reverse karaoke.

LaDiDa will spit out a recording of your enhanced voice and backing tracks.
Parag Chordia, Gupta's husband and Khush's chief technology officer, is a professor at Georgia Institute of Technology and director of the school's music intelligence lab. LaDiDa was developed there, Gupta said.

Whiz-bang technology is one thing, but to make LaDiDa a hit, it needed someone with an innate understanding of people's desire to put on a show. And no, that desire is not just about lots of sake. … Read more
